Sources and Authority

  • The Supreme Court has defined a manufacturing defect as follows: “In general, a manufacturing or production defect is readily identifiable because a defective product is one that differs from the manufacturer’s intended result or from other ostensibly identical units of the same product line.” (Barker v. Lull Engineering Co. (1978) 20 Cal.3d 413, 429 [143 Cal.Rptr. 225, 573 P.2d 443].)
  • “[A] defective product is viewed as one which fails to match the quality of most like products, and the manufacturer is then liable for injuries resulting from deviations from the norm …” (Jiminez v. Sears, Roebuck & Co. (1971) 4 Cal.3d 379, 383 [93 Cal.Rptr. 769, 482 P.2d 681].)
